Question

A box that weighs 200 N is at rest on the floor. If the pressure exerted by the

box on the floor is 20,000 N/m2

, over what area is the box in contact with the

floor?​

Answer 1

Answer:

0.01 m²

Explanation:

Given:

Weight of the box = 200 N (i.e, the force exerted by the box)

Pressure exerted by the box = 20,000 Pa

To find:

Contact Area of the box with the floor

Method to find:

Pressure = Force / Area

⇒ 20,000 = 200/Area

⇒ Area = 200/20,000

⇒ Area = 0.01 m²

Hence, the box is in contact with 0.01 m² of the floor.

Answer 2

Answer:

0.01 m2 is correct answer
